De Blasio interviewed by Manhattan district attorney's office

The mayor revealed the meeting at a press conference devoted to the Vision Zero traffic plan.

Mayor Bill de Blasio was interviewed by the Manhattan district attorney's office, he revealed at a press conference Wednesday.

Manhattan District Attorney Cyrus Vance has been investigating whether the mayor broke state election law trying to help Democrats win the state Senate in 2014, The New York Timeshas reported.

The mayor said he had not gone before a grand jury, but when asked to clarify if he had met with any investigators, he told reporters about a meeting with the Manhattan prosecutor's office "a few weeks back."

"To a grand jury no, no formal proceedings," he said. "The Manhattan D.A.'s office asked for an interview, [and] we did an interview."

By "we" he meant "me and my lawyers," de Blasio said.

With that, the mayor cut off the press conference at the corner of Atlantic Avenue and Fulton Street in Brooklyn, which had been devoted to his Vision Zero traffic plan but also included a shorter "off-topic" question-and-answer period, which he does once a week.

"Guys, I'm not going into any details, lawyers can fill in for you," he said. "I just told you the factual answer to your question. Thanks everyone."

The mayor and top aides have been the subject at least five separate investigations, according to the Times.
